Interfaces Not Updating Properly

[adparis99]

Hello,

I recently noticed that the following workflow no longer works on any devices:

• Select multiple interfaces (with mode already configured as tagged) and initiate a bulk edit
• Change the untagged VLAN
• Change the tagged VLAN (just one)
• Apply

When I look at the changelog, only the tagged VLAN is shown as having been updated. Looking at more detailed logs, I get the following errors, with other tracebacks sandwiched in between:

Exception while resolving variable 'parent_bay' in template 'dcim/device/interfaces.html'
File "/opt/netbox/venv/lib/python3.10/site-packages/django/template/base.py, line 880, in _resolve_lookup
current=current[bit]
TypError: 'Device' object is not subscriptable

...

File "/opt/netbox/venv/lib/python3.10/site-packages/django/template/base.py, line 903, in _resolve_lookup raise VariableDoesNotExist(django.template.base.VariableDoesNotExist: Failed lookup for key [form] in [large json array here]

By "no longer works", I should clarify that the GUI allows me to complete those steps, but upon loading back into the interfaces page on the device, only the tagged VLAN gets updated. I also thought it was strange I got the parent_bay error, as none of the devices I'm testing are configured that way.

I'm running v3.4.6, and the issue isn't replicable on the demo instance. Any thoughts/tips on what/where to look for the next troubleshooting clue? Thanks in advance.

Edit: grammar
